Shelby Houlihan is halfway to a fifth double at a national championships after taking the 3000m at the USATF Indoor Championships in Albuquerque on Friday night.
Houlihan, a Rio Olympic 5000m runner, extended her domestic distance dominance by clocking 8:52.03.
She led after every lap and prevailed by 1.67 seconds over Bowerman Track Club teammate Karissa Schweizer. Elle Purrier, who last Saturday ran the second-fastest indoor mile in history, was fourth in 8:56.56.
Houlihan has won a pair of titles at four separate national championships — twice indoors and twice outdoors.
